I'm studying etymology, analying prefix and suffix of words. Are "abduct" and "kidnap" interchangeable? abduct's ab is said to mean "away, off", while "kidnap"'s "kid" is related to children. But you use "kidnap" even if you kidnap old people. Do you use "kidnap" only for children, while "abduct" in general?
ex)He(abductor) abducted(kidnapped) the little girl in her house at dawn.
The link charlie shows me an explanation by Ouisch that "abduct"'s purpose is usually revealed after recovering the abductee, while "kidnap"'s is known after the kidnapping happens.
So is the difference the point of revealing the purpose or are they interchangeable?
